Where the two differ is the whole answer. BEV and ICE rarely differ on every line; the decision lives in the two or three bars where they do. Ordinal comparison consistent with the total-cost-of-ownership literature cited on this page.

Powertrain comparisons in the total-cost literature reach different winners in different markets and at different mileages, and that is the finding rather than a failure of the studies: the answer genuinely depends on the inputs [1]. The lines below are where these two part company.

Where BEV and ICE differ
LineBattery-electricPetrol
DepreciationThe most volatile residuals of the three: early generations, list-price cuts and fleet waves all hit hard, and battery state of health is becoming a priced attribute. A documented pack holds value; an undocumented one inherits the segment’s worst assumptions.Well understood and stable — but watch the policy direction: as low-emission zones and CO₂-based taxes spread, higher-emission used cars face a slowly narrowing market in several European cities.
Energy / fuelSplits into two lines — off-peak home charging and public rapid charging — at very different unit costs. With a driveway, by far the cheapest per kilometre; without one, much of the advantage can go. Winter raises consumption, mostly through cabin heating.One line, one price, rising in step with distance. No cheap-tariff option exists.
InsuranceHas run higher than combustion for comparable cars in several markets — repair-network scarcity, battery-replacement risk and higher purchase price all feed premiums — and is narrowing as the fleet ages and repairers catch up.The reference point the others are compared with.
MaintenanceFewer moving parts, no oil, less brake wear from regeneration: routinely the cheapest to maintain. Tyres wear faster under the weight and torque, which is the one line that goes the other way.Middle of the pack, rising with age and mileage in the familiar way.
Tax & feesWhere registration or company-car tax is emissions-weighted, the structural winner by construction. Where EV-specific road fees have been introduced (Iceland, some US states), the advantage is smaller than the headline suggests.The structural loser under CO₂-weighted registration and company-car regimes — which in several markets is now the largest single cost difference against an EV.

On financing cost the two behave much alike, and those lines will not decide it.

What decides it

For BEV: Wins on total cost most clearly for a driver with home charging doing typical-to-high mileage in a market whose tax system rewards low emissions. Loses most clearly for a low-mileage driver without off-street parking.

For ICE: Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten.

The comparison shifts with annual distance — see Battery-electric at each mileage and Petrol at each mileage — and with the tax architecture of your market, described on the country pages.

What you control after buying

The energy line of any total-cost estimate is the one you control after purchase. Home charging on an off-peak tariff and motorway rapid charging can differ several-fold per kilowatt-hour, so where you charge on long journeys moves the annual number more than the badge does. Drive Charge Eat plans stops around cheaper, reliable chargers that also have somewhere to eat.

Is BEV or ICE cheaper to own?
It depends on charging access and annual distance. Wins on total cost most clearly for a driver with home charging doing typical-to-high mileage in a market whose tax system rewards low emissions. Loses most clearly for a low-mileage driver without off-street parking. Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten.
Which holds value better, BEV or ICE?
BEV: The most volatile residuals of the three: early generations, list-price cuts and fleet waves all hit hard, and battery state of health is becoming a priced attribute. A documented pack holds value; an undocumented one inherits the segment’s worst assumptions. ICE: Well understood and stable — but watch the policy direction: as low-emission zones and CO₂-based taxes spread, higher-emission used cars face a slowly narrowing market in several European cities.
